VOX FOCUS 100 PUBLIC ADDRESS SPEAKERS - 1971
Designed by "Vox Sound Limited" in 1971, these were the bigger brothers of the standard "Focus" speakers (40-50 watts), which had been created by "Vox Sound Equipment Limited" in mid 1969 - as ever, in time for the August equipment show in London. Standard "Focus" units can be seen on this page.
Portability was a key concern. Pairs of columns could be latched together with their clips and carried as a single unit by the handles provided.
The Focus 100 Linesource speakers first make their appearance in a notice published in "Beat Instrumental" magazine, July 1971, presumably having been developed for the Associated Musical Instrument Industries show in August (the A.M.I.I. being the successor organisation to the British Musical Instrument Trade Fair).
Section from the Beat Instrumental notice. The Focus 100s cost £120.00 in July 1971, no small amount.
